Description: These artichokes came directly from an elderly Dalmatian gardeners garden, right on the shores of the Kaipara Harbour near Pouto. The site chosen by an early Ships captain to make home and build the first commercial store on the Kaipara.. and where there already existed in 1840, large Maori orchards of acres of peach trees!

Planting Instructions: Prefer free draining, well composted or manured soil. Plant tubers direct into soil when ground temperature reaches 15 – 16ºC. We plant them at approximately 40 cm spacings in two rows along a 1 metre wide bed. They are ready in winter when the tops die back and can left in the ground until they are going to be eaten as long as the ground is not too wet. In early spring dig up all that remain in the bed, prepare the bed and replant. Alternatively they can be dug up when tops die down and stored in damp sawdust and the bed re-planted in the spring.
